anyone know a quick way to convert either kilos - miles or visa-versa I am trying to do some track work and would appreciate any help


  • Nigel,

    I'm not sure that this is the answer you're looking for, and the figures are approximate, but to go from kilometres to miles I use the following:

    To get miles, I multiply my kilometres by 0.62

    To get kilometres, I multiply my miles by 1.61

  • As a rough guide, 5miles is 8 k, so 10 miles is 16k...then you can divide up other distances
  • MuttleyMuttley ✭✭✭
    To use some runner-friendly distances, 5K is roughly 3.1 miles so 10K is nearly 6 and a quarter miles. A half-marathon is just over 21K.
  • DustinDustin ✭✭✭
    Unless you need it too accurate
    Miles to kms x0.6 (or x5 and divide by 8)
    Kms to miles x1.6 (or x8 and divide by 5)

    or you could do what I do and use (race pacer) plug in either kms or miles and it gives you the miles or kms equiv back .

    also depends on how good your basic maths is.(I believe if you can now multiply by 8 and divide by 5 you get automatic grade A at GCSE).
  • That's a bit below the belt about students' GCSE ability Dustin. Many students work hard for these results and working in a senior school I can tell you they certainly need to be able to do far more than you believe.

    What do you teach?

    I always wanted to be a teacher but - and shocking to say I know - it didn't pay enough money.

    My daughter has just taken the incredibly brave plunge of switching to a German speaking school (she was previously in an international English speaking school), so now all her lessons are in German! (Un)Fortunately German and English algebra are still just as hard (for me!)
  • If you are running on a track, 400m is just short of 1/4 mile - 0.2485 to be precise! So 4 laps is just short of a mile (0.9942).

  • Hi Martin,
    I'm not a teacher as in class teaching, I'm a Dyslexia Therapist working in a specialist unit within a senior school. Very rewarding but poorly payed!
  • Jo - presumably that is the inside lane on a track. Do you know how much extra distance is added by going one lane further out?

    Perhaps running in the second lane would make it an exact 1/4?

  • Yes, that's for the inside lane - I'm not sure about the other lanes. However, I recall seeing something about that on the training forum a couple of weeks ago - maybe worth a search?

  • How accurate do you want to be? For training on the track, i usually say 4 laps is one mile - only the sprinters are allowed on the inside 3 lanes at our track on a Club night, so by running all the way round in tracks 4-10, i must be doing a full mile plus a bit in 4 laps.
    The bit extra i count as the 'bit for luck to make me faster!'
  • Does that mean then Jo that the world 400m record isn't actually for 400m?
  • Gee - I don't know - this is all getting too technical for me! They do stagger the start line though don't they?

    (BTW - I saw on another thread hilly that you are a dyslexia therapist - I hope you know how appreciated you are - I've 2 dyslexic kids, one of whom has just 3 Bs at A level which a few years ago we would never have thought possible.)
  • Hilly

    I think you misunderstood the thread. A mile is actually 1,609.34 metres, therefore 4 x 400 metres would be slightly less than a mile and 400 metres is slightly less than one-quarter of a mile.

    Or am I taking things too literally.
  • I could well have done Martin, it has been known to happen!:)

    Thanks Jo and congratulations to your son, it's always nice to hear of success stories.
  • You're all giving me a headache! Maths was the one subject I dropped in school. To convert kms to miles (unless you just have to have it accurate to the nth place) simply multiply by 6 and add a little bit. For instance, 10km is exactly 6.2 miles, 20km is 12.5 miles, 30km is near enough 19 miles. Not very scientific but it works.
  • kms to miles - times 5 divide by 8
    miles to kms - times 8 divide by 5

    simple sums.
  • Easy way Kilos to miles just take of 1/3. Not 100% accurate but near enough also works for £ to Euros and £ to $ at the moment
  • PB - after so many years living in Germany and working with Americans I don't convert them. I have a measuring scale that shows both kilos and pounds, and a set of American measuring cups for American weights.
  • But how many Angstroms are there in a chain? That one always throws me.
  • Nigel - why bother converting? Just stick to either metric or imperial and work with that - preferably metric in my view (see another thread about this). Don't see any point in working with both measures.
  • yes there is - we live in a country which uses both sets of units & run races measured in either
  • Exactly - it's about time the UK got rid of imperial as it's not taught these days; apart from pints in pubs you can't buy anything measured or weighed in imperial; so why we have to persist with it is beyond me.
  • How old are you FBF? This may be an age-related thing.
    I'm 43, and while I'm q capable of coping with either set of units, I still tend to think instinctively in terms of the imperial version for most things - they were the only units in town when I was growing up.
    E.g. on a warm day I tend to think of temperatures as being in the 70s rather than the 20s.
    As previously stated, minutes:seconds per mile is a pace (and effort) level I immediately have a feel for (and, to a lesser extent, seconds per lap).

  • Sorry Mike - I'm older than you - 49 in fact. I gave up with imperial a few years ago as a conscious effort. I also find metric so much easier to calculate with. I'm at a loss to understand how those taught in metric want to use imperial measures. Just seems daft. The only imperial measure I can't do without is pints - beer for the use of!
  • P.S. Would one of those "youngsters" taught in metric provide some explanation of why they want to use imperial? I'm curious.

    How about the Epsom Oddballs 2000 Perch on Jan 19th? A pb distance for sure..... It's in the RW race listings.
